[U-Boot] [PATCH 2/3 v2] mmc: control message print in find_mmc_device

[Thomas Chou]

An argument, verbose, is added to enable/disable the "Device not
found" message. Because we need to query mmc devices in mmc_spi
subcommand and don't want the message.

v2: add an argument instead of add a new func, per Wolfgang.
